Abstract
Abstract of the Disclosure A dosage control device, particularly suited for use by persons with impaired vision who from time to time may give themselves injections such as diabetic. The dosage control device is a sheet like, elongated plastic member having a trans-verse slot for snapping over the finger projections on the end of a standard hypodermic syringe. A scale is provided in a pre-determined disposition with respect to the slot so that when the device in conjunction with the outer end of the plunger duplicates the normal scale on the syringe. In use, a doctor or other person would cut off the outward extending end of the device at the scale marking for the desired dosage, so that the diabetic could control his dosage by feel rather than sight.

~ Detniled D~s~ription of thc Invention , First referring to PIGURE 1, a plan view of ons embodiment of the present invention may be seen. Tho dev~ce 20 of this embodiment is characterized by an elongated plastic sheet-like member S ~, which in the preferred embodiment, is a vinyl sheet having a thickness of approximately thirty thousandths of an inch. There is located adjacent one end a transverse slot 24 of predetermined ~ and controlled dimensions. A scale 26 is provided in a predetermined i~ spatial relationship with respect to slot 24, the scale in this ~.
-` 10 embodiment ranging from 0 to 100. While the member 20 is sub-;~ stantially rectangular, the two ends 28 and 30 are specifically - given different geometries, so as to be readily discernible by feel ~ -of the person using the device. It is particularly important that ~-the end 30 be given some geometry substantially different than the -~
geometry which will result at the other end when the device is cut off for use, as shall subseguently be described, and accordingly in this embodiment the end 30 is given a non square characteristic, unlike the end 28. Finally, in thi- embodiment there is a space provlaed betw en slot 24 and end 30 for cert~in printed mRtter, ;~ 20 lncludlng the identification of the type and nature of the drug to b- used if the scale 26 is ~arked off in units or ~ similar designation.
Y -Now refersing to FIGURE 2, a perspective view of the present invention mounted on a standard plastic syringe may be seen.
It w~ll be noted that when the device of the present invcntion is ~ounted onto a standard syringe 32, the outer end 34 of the plunger cooperatively disposed with respect to the scale 26 on device 20 of the present invention. More particularly, when the plunger is ln lts inne.wvst~posit1on, e.g., the zero dosage condltion, th -end 34 of the plung¢r is also at the zero position on scnle 26;

of thc plunger in cooperation with thc scale 26 will always provide the same reading as would be obtained with the scale on the cylinder. Accordingly, by cutting off the device 20 at the scale reading for the desired dosage, a person of impaired S vision may control the dosage by using the end of the device 20 in cooperation with the end 34 of the plunger as a gauqe or stop while loading the syringe with the druq to be administered.
Now referring to Fig. 3, a side view of the assembly of Fig. 2 may be seen. It will be noted that the flanyes of the syringe, generally indicated by the number 38, are comprised of radially outward extending members 40, with a forward extending bead or lip 42. Also, it will be noted in Fig. 2 that the sides 44 of the flanges are flattened so that the bead g2 is an arc segment, as may be seen in Fig. 4. This arc segment on conventional syringes is disposed with respect to the cylinder 32 so as to all~w the dispnæition of the device 20 between the cylinder-32 and the lip 42, as may be seen in both Fig. 3 and Fig. 4 without requiring any curvature of the device 20 along a longitudinal 2Q axis. It is to be understood, however, that the present invention -may be curved along a longitudinal axis, with the curvc providing lncreased rigidity of the device of the present invention without resulting in cracking or fracturins when being bent about a transverse axis. In the pref-rred embodiment slot 24 has ~ widtn to freelg ~t ~losely accommodate the widest area of the ~lange 38 on the cylinder 32.
~ow referring to Fig. 5, the slot 24 in an alternate ~embodiment of device 20 is comprised of a transverse section 46, ~nd longitudinally extending sections 48 at the outer extremities of the transverse section so dS to define a tab like me~ber 50 ~or ~napping over the lip 42 on the flange 38. Accordingly, though the transverse slot 46 may be-made slightly wider than the '~

: ,;
thickness of the radially extcnding mcmber 40 of flange 38, this embodiment of the device may be snapped into place on the syringe and will retain itself in that position by the snapping o tablike member 50 over the lip 42.
S Now referring to Fig. 6, a top view of the assembly ; of the device of the present invention and a standard syringe, after the device has been cut off at a predetermined dosage level, -may be seen. In particular the device as shown has been cut off to allow the control by feel of a dosage representing 50 units.
j 10 - It will be noted that when cut off st such a position, the linear dimension from slo~t 24 to end 52 is not substantially different from the linear dimension from slot 24 to end 30. ~owever, it is very clear that the two ends are readily distinguishable by ' feel, and that there is substantiaily no opportunity for a user i 15 to mount the device onto a syringe incorrectly.
There has been described herein an extremely simple device which may be used by perfions of impaired vision to control ~ Jelf-administered dosages of drugs by standard hypodermic syringes.
;; The device of the present invention may be manufactured st extremely low cost, and reliably set to the desired dosage ~e.g., cut off at .
- the required length) to provide a substantially foolproof method of gauging that desired dosage. The present invention may be very easily carried by a user and may be used in conjunction with ~tandard syringes without any modification thereof. While the preferred embodiment has been disclosed and described with respect to ~tandard plastic syringes, it will be noted that the device may ~readily be changed, particularly in proportions, so as to be usable ln like manner with glass syringes. In that regard, the flanges on the cylindcrs of glass syringes are very similar to the flanges ~described horcabove with respect to plnstic syringos, o that the :.

device o the present invention may be readily made to snap onto the flange of a glass syringe in the same manner as described herein.
While the preferred embodiment of the present inven-tion has been disclosed and described herein, it will be noted that a number of modifications and additions may be made thereto.
Aside from providing a curvature about a longitudinal axis as previously described, other changes may include some form of clear identification of the drug to be used therewith, such as, by way 0 of example, some form of stamped or embossed designation which would be readily detectable by feel. This may be accomplished by embossing the drug designation into the plastic. It may also be :, . .
accomplished in a very inexpensive manner by making the shape of end 30 unique with respect to each drug for which such devices `lS are fabricated, so that the gross appearance and gross feel of the device provides an immediate identification for its intended use.
Thus, while a present invention has been disclosed ,~ and described with respect to a preferred embodiment thereof, it will be understood by those skilled in the art that various changes 20 - in form and detail may be made therein without departing from the spirit and scope of the invention.
